To calibrate the PANORAMA listening mode:

1.Remove all obstructions between the speakers and the primary listening position.

2.Make sure the distances between the speakers and the primary listening position are properly measured. To do this, select one of the following options.

•Select the AUTO SPEAKER SETUP menu DISTANCES option to have the MC-12 automatically calibrate speaker distances.

•Measure the distance between the primary listening posi- tion and the front baffle of each speaker. Then, set the cor- responding SPEAKER DISTANCES menu parameters to the closest available value.

3.Sit in the primary listening position. If the primary listening position is not centered between the front left and right speakers as shown in illustration B (above), set the PANORAMA

buttons. Each increment within the –127 to +127 parameter range represents about one-third of an inch. Illustration A shows the left of center position. Illustration C shows the right of center position

4.Set the SOURCE parameter to RIGHT.

5.Begin playback of the external calibration source.

6.When playback of the external calibration source is in progress, set the SPEAKER ANGLE parameter so the sound is not heard in the right ear.

7.To confirm the LISTENER POS and SPEAKER ANGLE parameter settings, set the SOURCE parameter to LEFT & RIGHT. If the PANORAMA listening mode is properly calibrated, the sound should be perceived to come from all around the primary listening position. If not, go back to Step 1 and repeat the cali- bration procudure.
